Description
Technical field
The invention belongs to technical field of automobile, more particularly to a kind of single-row roller bearing.
Background technology
Roller bearing is the rolling bearing for making rolling element with short cylindrical, circular cone or drum-shaped roller.Mainly there is centripetal short circle
The structural shapes such as post roller, double-row spherical roller, taper roller and thrust roller.Common roller bearing is by bearing internal external
The retainer for enclosing and being arranged between, roller is arranged on retainer to be used to separate each roller, keeps roller spacing
It is equal, make load mean allocation.But existing roller bearing is existed when in use：Stability is poor, and bearing capacity is poor, installs
Inconvenience, roller end is easy to wear with outside, and service life is short, roller lubrication degree difference the problems such as.
In order to solve the problems, such as prior art, people have carried out long-term exploration, it is proposed that solution miscellaneous
Scheme.For example, Chinese patent literature discloses a kind of wear-resisting type cylinder roller bearing [application number：201110119547.X], it is main
To be made up of bearing race, bearing blowout patche, roller and retainer, it is characterised in that：The roller is two row and row cylinder roller
In retainer, the retainer is provided with a flange, and two row and row cylinder roller and retainer are in integrative-structure
On bearing race, the bearing axle snare is in two row and row cylinder roller on the integrative-structure with retainer.
Above-mentioned scheme improves the subproblem of prior art to a certain extent, for example, solving to a certain extent
Retainer problem easy to wear, but, also at least there is following defect in the program:Stability is poor, and roller installs inconvenience, roller
End is easy to wear with outside, the problem of retainer lubricity difference.
